Correction!....oops Im sorry I'm ADD plus high, lol. But here what u need to do.
1) 8 day old lill dingling dosen't need strong light. 60 W CFL daylight will do the job very nicely. You need to give it a chance to start the new roots. Adjust your ph to 5.85 with 100 ppm.
You will be good to go. I will post a link for you later on which it will give you a good idea how to grow in coco.
Peace
